About the Authors

Adrián Sergio Pulvirenti was born in Buenos Aires, Argentina, in 1972. He earned his Bachelor's degree in Computer Sciences at UBA, one of the most prestigious universities in South America.

He has dedicated more than 15 years to developing desktop and web-based software solutions. Over the last few years he has been leading integration projects and development of BI solutions.

I'd like to thank my lovely kids Camila and Nicolas, who understood that I couldn't share with them the usual videogame sessions during the writing process. I'd also thank my wife who introduced me to the Pentaho world.

I'd like to thank those who have encouraged me to write this book: On one hand, the Pentaho community. They have given me a rewarding feedback after the Beginner's book. On the other side, my husband who without hesitation agreed to write the book with me. Without them I'm not sure I would have embarked on a new book project.

I'd also like to thank the technical reviewers for the time and dedication that they have put in reviewing the book. In particular, thanks to my colleagues at Webdetails; it's a pleasure and a privilege to work with them every day.
